COMBINATION METAL-WORKING MACHINE.

Application filed August 12, 1918. Serial No. 249,425.

To all Mitt/ill it WZf/ l/COHLYTTH1' Be it known that I, Wimznn J. PINE, a citizen of the United States, residing at Oshlmsh, county of Winnebago and State of Visconsin, have invented new and useful Improvements in Combination Metal-Working Machines, of which the following is a specification.

My invention relates to improvements in combination metal working machines.

The object of my invention is to provide an improved machine capable of performing the functions of a lathe, a milling machine, a shaper. and a grinder.

In the drawings:

Figure 1 is aside elevation of a machine embodying my invention.

Figure 2 is a similar view, partly in vertical section, exposing the carriage, and with the head partially broken away to expose the carriage operating mechanism.

Figure 3 is an end elevation showing the head column and. associated parts.

Figure 4 is an end elevation showing the tail stock removed.

Figure 5 is a detail view of the reversing mechanism for the longitudinally movable carriage. I

Figure 6 is a fragmentary plan view of the head stock and back gear mechanism showing the connections for operating the grinding wheel.

Figure 7 is a fragmentary rear view showing a portion of the driving connections of the. grinding mechanism.

Like parts are identified by the same reference characters thruout, the severalviews.

My invention includes all of the essential features of an ordinary engine lathe, viz the head and tail columns 1 and 2, the head stock 3. tail stock 4, bed 5, carriage 6, cross head manual and automatic means for reciprocating the carriage and cross slide,

including the manually operable cranks 8 and 9 and the power driven shafts 10 and 11, the latter being operatively connected with the spindle 13 by any suitable power transmitting mechanism located in the gear box 12, (Figures 1 and a suitable back shaft 14, with ordinary gear connections with the spindle, and suitable clutch mechanism being also employed in conformity with established practice.

But it will be observed that the lathe bed 5 is supported by screws 20 and 21 and is tail column and associated parts with the.

arranged to slide in suitable guideways formed in the head and tail columns 1 and 2. The screws 20 and 21 have threaded hearings in posts or columns 24, whereby a rotation of the screws will raise or lower The power shaft 11 drives the main feed screw 36, shaft 11 being flexibly jointed at 40 and 41, universal or double knuckle joints with telescope shaft being employed, in or der that the table with the feedscrew 36 may be raised and lowered without discon necting the power.

Shaft 10 is similarly universally jointed I at 42 and 43. This shaft isemployed to reciprocate the carriage and cross slide when the device is being operated as a lathe, motion being transmitted in one direction to the rack engaging pinion 45 thru the bevel gear wheels 46 and 47, (Figure 5), pinion 48 carried by wheel 47, gear 49 driven by pinion 48, gear 49 which is adapted to be manually engaged by handwheel 51 with gear 49 thru clutch disk 50, and gear 52 upon which is mounted. rack gear 45. The rack gear 45 can also be operated manually thru hand wheel 8 which carries gear 8' engaging with gear 52. The cross slide 7 may be mechanically driven by using hand wheel 151 .to move gear wheel 152 to a position where'it will enmesh with gear 49. Gear 152is also engaged with and adapted to drive gear 153 which .may be turned manually by the crank 9 This gear in turn drives 1'54 and 155, the latter being fast to the crossfeed screw 156.

But it will be observed that the pinion 46 is mounted upon a sleeve 62 connected with a shifting slide 63 adapted to engage stops 64 and 65 at the respective ends of the field of movement of the carriage. These stops may be supported from the shaft 10, as shown in Figure 5, there being suflicient clearance to allow them to rotate with the shaft. It is not material, however, whether they are supported on the shaft or from any fixed point on the machine. The slide 63 is mounted on the carriage apron, and,

assuming it to be moving in the direction of the a row in l igure 5, it is obvious that, when slide strikes stop (55, it will be shifted in direction to carry the beveled pinion out of Contact with the bevel gear wheel t and to simultaneously carry another bevel pinion 67 into close proximity with the bevel gear wheel 47 on the opposite side of shaft 48.

In order that the bevel pinions d6 and 67 may le automatically advanced into mesh with bevel gear 1 7, I employ the T-shaped trip 70 connected with the apron by the link rods '71 and T2, at the pivot pins 78 and 7 the linl: rods being: formed in extensible sections tch tend to spread under the pressure compression springs 75, the a rangement beine; such that the springs will be comp. d when the head of the T-shaped member 70 is at he line of centers thru the pivot pins 75 and 74. Upon crossing said line, the springs will react and ce-operate with tile stop 65, (or (i l). in shifting the slide 63 to its proper position with one of the pinions 6?, (or 4.6), in engagement with the bevel gear wheel 17, the pinions being then held in such position by spring pressure nntil the carriage has traveled in the opposite direction to the limit of its stroke and into engagementwith the opposing stop for another shifting movement of the slide 63. This results in an automatic re verse of carriage suitable for grinding arbors.

The object of adjusting the table verti- Cally is to facilitate the use of the machine as a milling machine, and increase or diminish the swing of lathe and clearance. It will be observed that the spindle is provided with a chuck receiving nose 80, extcriorly th eaded and also socketed. whereby it is adapted to receive a chuck having a threaded socket or centering point 81. The head stock also extended upwardly far enough to receive an ov i'in 8h prov d with. a brace adj b y mounted tereon and adapted to provide an outboard bearing for an arbor. (one end of which would be ena'aned by the spindle nose 80). Owing to the fact that the bed is vertically adjustable, the

carriage lonpitud-inally movable, and the cross slide 7 transversely movable. it 1s obvious that all of the adjustments and move ments required for milling operations are obtainable. ll hen not in use. the brace 84 may be rotated upon the iverarm 83. and tie latter retracted if desired, is common in milling machine practice. Therefore neither the overarm nor the brace will interfere with lathe work or zrindin operations.

In order that the device may be adapted for use as a planer, I have provided a center slide 90 having notches 91 in its upper surface. The carriage is transversely bored and adapted to receive a cross rod. 92 having ry circle groove concentric with the spindle. indicated at 89, whereby the chuck may be rotatively adjusted. The tool course. be supported upon the slide e usual manner.

Slide 90 may be operated from the slow 95 of the back gear mechanism thru on 96, shaft 9?, gear wheels 98 and 99, (-35 degree gears). crank pin 100, bearing member 101. lever 102, and link bar 103, the latter connecting the upper end of lever 102 with slide 90. Lever 102 is pivoted to the foot of the head column 1 at 105. Crank pin 100 is connected with the gear wheel 99 and carries a roller bearing member 101 which travels in a slot 107 formed in the le er 102. The crank pin 100 is preferably l stably mounted in a radially extending sl 109. whereby this crank pin may be moved toward and away from the center of rear wheel 99, thereby varying the length of stroke transmitted to the slide 90 and the arrian e. It will, of course, be understood that crank pin 100 will be anchored in the desired position of adjustment in the slot by an ordinary clamping set screw or anv other suitable means.

Pinion 96 is adapted to be shifted on shaft 97 into and out of engagement with; the drivint: member on the spindle. (and which constitutes the driven member of the back gear train). by means of a manually operable crank 112 located exterior to the column .1 but having a stud shaft. 13 extending thru the wall of the column and connected with a gear shifting arm 1.15 within the column. as clearly shown in Figure 2. Therefore. gear wheel 96 may be readily shifted to an inoperative position. and the carriage may. with equal facility. be released. from sl do 90 by withdrawing: key-rod 92. after which. the criapge may be reconnected with the feed screw or with the reeprocatin r mechanism driven by shaft 10.

l otion is transmitted from the spindle to the screw actuating shaft 10 thru ordinary gearing within the gear box 12 as indicated by dotted lines in Figure A belt 120 also indicated by dotted lines transmits motion from the spindle to shaft 11. These connections are adapted to transmit motion at re duced speed.

But for operating the grinding Wheel 122 (Figures 3 and 6), a high speed motion'is transmitted from special spindle pulley carried by a swinging arm 128, and a lever micrometer 1&0 has a forked short arm 141 loosely engaging with the pulley shaft 142,- whereby these pulleys, (127 and 130), may be swung about the axis of shaft 132 as a .center to distend or slacken belt129. When the belt is slack no motion will be transmitted.

It will be understood that the grinding wheel is mounted upon the lathe carriage. When the grinding wheel is thus. operated H in connectionwith' the automatic carriage reversing mechanism, above described, it will be obvious that work mounted on the lathe centers, (i. e., arbors, for example), can be ground with the accuracy of the adjustments commonly provided for engine lathes.

In the construction above described, I am enabled to utilize various changes of speeds and feeds of an engine lathe for the various purposes set forth, and I have therefore provided a combination machine which is practical for a wide range of work, but which will occupy no greater floor space than an ordinary engine lathe. I have also provided means whereby all of the various mechanisms may be driven from a single source of power, operatively connected in common, and subject to all micrometer adjustments commonly used.
